As per Article 368 of the Constitution of India, the Parliament may amend any provision of the Constitution by way of : 1. Addition 2. Variation 3. Repeal Select the correct answer using the code given below:

Article 368 of the Constitution of India deals with the power of Parliament to amend the Constitution and the procedure for doing so. An amendment implies changing the existing provisions, which can involve:

1. Addition: Correct. Parliament can add new provisions to the Constitution. For example, the addition of Fundamental Duties (Article 51A) or Part IXA (Municipalities).

2. Variation: Correct. Parliament can modify or change existing provisions of the Constitution. This involves altering the language, scope, or impact of an existing article or part.

3. Repeal: Correct. Parliament can repeal or delete existing provisions of the Constitution. For example, the right to property was removed as a Fundamental Right and made a legal right. This effectively repeals its status as a fundamental right from that part of the Constitution.

The term 'amendment' itself, in constitutional law, encompasses all these forms of change. The Supreme Court, in various judgments, has affirmed Parliament's power to amend the Constitution through addition, variation, or repeal, subject to the Basic Structure Doctrine.

Therefore, all three are correct.
